ABSTRACT:
An image processing apparatus decomposes an image into frequency components of at least two frequency bands, and generates a basic conversion table used to change values of the frequency components. The image processing apparatus sets an expansion/contraction ratio of the basic conversion table on the basis of a pixel value range which is determined on the basis of the image. The basic conversion table is changed based on the set expansion/contraction ratio.
